Great to begin with but...
Let’s get the positives out of the way first. Lovely earbuds, comfy fit and sound quality is excellent. Bluetooth connection was really easy and no problem to set up. Charging case also of good quality and again easy to use. Unfortunately after less than a week of use, the right ear bud stopped working and would not charge. No lights - nothing. Having looked online at how to fix the issue, it would appear that this is a common issue and I have been left with no option but to return to Sony for repair. Hugely disappointing as these really are great earbuds and I love the design and features etc. Hope the quality and reliability of future releases is much better.

Charging speed
As i use this earphone in daily basis and almost all the time, the battery life of the earphones is considered sufficient for me, but the charging of time for the earphones' case may take quite the time, it is longer than my phone charging speed. Hope you can improve the charging time of the charging case to match with the latest phone charging speed.

Overall all the functions and qualities meet my expectation on the product. But I only have a little issue in bluetooth connection problem. But it wasn't a big deal of a problem. Next, the earphone is quite uncomfortable to wear for me at least, as it's considered quite big for my ear, so the smaller size of ear plug rubber really help solving this problem.

Great sound.... from the left ear
I’ve had the product for less than 3 months. Already the right earbud is having connectivity issues. It cuts in and out and has happened more often the longer I’ve had them.

Sound is crystal clear. Bass is deep and strong, mid tones are well balanced and high tones are crisp. Callers can hear even with face mask (they said 'muffled' but they can still hear), great design, great feel and weighty without hirting ears (case is perfect), battery charge is long in buds and from case, they never fall out no matter what your doing because they actually 'screw' into your ears (push in and screw back - to take off screw in opposite direction).  Good noise cancelling (shop assistant behind me had to tap my shoulder to get my attention). Good value for money (use a sound equalizer like Power Amp to get the most rich sound possible).

Good sound, bad syncronization
So, i had these for about a week. Purchased from "that" auction site. These were brand-spanking new. Before i first used them i charged them up for 8 hours, they worked fine but i now see that the right earpiece takes longer to charge than the left and the charge runs out fairly quickly, at around 2 hours or so. This causes a sync' issue and i find i have to re-sync them almost every time. The earpieces are either in my ear or in the charging case so i cannot understand why 1 doesnt charge / remain charged. When they work the sound is very good, especially for my tinitus (which is very bad) i'm no audiophile, i just like to hear my music. These earplugs offer NO control over either a samsung phone or shanling mp3 player. You have volume but no pause, previous or next track control which, for this price range is disappointing. I have to add stars and a "would i reccommend" note.... 4 stars for sound, no stars for control and negative stars for reliability. This is sad as i used to only buy Sony products but it seems that they have let things slip somewhat. Would i reccommend? If they work then yes. (There isn't a 3rd choice here!!)

Don’t call Anyone!!
I purchased these a couple of months ago and while I am ok with the quality of the sound when I am listening to music they absolutely suck when it comes to making a call . There is no noise canceling at all. Everyone that I talk to complains the whole time about background noise and how loud it is. I would have thought by now that noise canceling is a standard feature but I guess not. Waisted a hundred bucks.

Great failures
Received it as gift, after a few uses BT failed. Item under warranty, so I got a replacement.
Replacement is defective and previously used. Ear tips different color than original.
Really disappointed of Sony
Sound balance is good

Good bass enhancement
I bought this for running. I like the bass enhancement, but it’s a bit big for comfort, so I do not recommend this if you want to wear it for a long time. Overall it’s good for its price.

Super value for money
Bought this 3-4 weeks ago after years of struggling with the fit and sound and battery life of other wireless phones, these fit me well, tightening the fit if and when it starts to slip is an easy twist, sound is clear, battery life, hasn't run out of me yet, charging case adds more battery life and security.
